. application filed May 21, 1909. Serial No. 49?,401.

To all whom it may concern:

' Be it known that I, SAMUEL WARREN Po'rrs, a citizen of the United States, residing in the borough of Manhattan, of the clty, county, and State of New York, have invented certain. new and useful Improvea specification.

This invention relates to registers or counters and has for an object to provide improved means for setting the number-wheels at zero.

In the drawings accompanying and forming a part of this specification Figure 1 is a longitudinal sectional view of a practicable embodiment of a form of my improvement, this section being taken on a plane represented by the line 11 in Fig. 3. Fig. 2 is a detail view illustrating the clutch mechanism; which is illustrated in Fig. 1 in its open position; in its clutching position. Fig. 3 is a cross section taken on the line 3-3 of Fig. 1, looking toward the right. Fig. 4 is a cross section taken in a plane at about the line H of Fig.- 1 looking toward the right. Fig. 5 is a view similar to Fig. 1 showing the catch or spring pawl member in a different positionrelative to its actuator than the position which is illustrated in Fig; 4. Fig. 6 is an end view of one of the number-wheels removed. Fi 7 is a cross sectional view of the number-w eel shown in Fig. 6. Fig. 8 is an end view of one of the driving wheels. Fig. 9 is an edge view thereof partly broken away. in cross section; and Fig. 10 is an enlarged detail of one of the catches and its actuator.

There is illustrated a casing 10 which partly constitutesthe frame work of the device. Mounted within the casing is a series of number-wheels 11, 12, 13, 14c and 15. The general form of the device is such as that illustrated in United States Letters counter and, as in' such patent, the present improvement is shown in connection with such a counter as will be operated by an oscillatory or rock shaft movement, there being shown a rock shaft 16 mounted in a bearing 17 of the casing 10, and adapted to be arm 18. The casing or framing member supports interiorly a hub or boss 19 which wheels four of which 21, 22, 28 and are shown in Fig. 1, the fifth wheel is'hidden from view in this figure by the number wheel 15. The driving wheels are rotated in the well known manner. One of the differences between this structure and that shown in the patent above referred to is: in the patent the number-wheels find a bearing on the said boss or hub, whereas herein each of the number-wheels finds a bearing upon the driving wheel which is within it.

In operation the first of the driving wheels 21 will be rotated step by step by means of the pawl 27 carried by the rock arm 28 which is on the shaft 16, and this driver is prevented from being moved backwardly by the detent 29, as in said patent. The connectionbetween each of the drivers and its number wheel is effected by means of a catch 30, in thepresent instance the catch is shown as a spring member which has a portion 31 suitably bent and set in a slot in the flange portion 32 of the number wheel, the intermediate portion 33 of the member is resilient and carries a by-pass spring finger 3 1,

presently to be described. The catch portion 30 will seat innotches 35 in the driving ever, shown as chamfered from a point considerably above the bottom of the notch to the top thereof for permitting the catch to ride out of the notch'when raised by its actuator in the manner described when the number-wheels are being returned to their Zero position.

For the purpose of setting the number- 'wheels to zero position a plate 37 is shown mounted inside of the end plate 38 of the casing and which plate has a hub 39 mounted inside of the hub d0 of the plate 38. The hub l0 supports a shortshaft 41 which has on its outer end a knurled head 42 and on its inner end a clutch member 43 provided with a recess for engaging with a projection 4: 1 uponthe plate 37. These clutch members will be moved into and out of engagement one with the other upon the reciprocation of the shaft 41, which shaft is provided with a number of grooves 45 and 4:6 for the engagement of a spring rin 17 which, by virtue of the fact t at it is held between portions of the end plates 3'2 and.

jcction 50 thereon will under the spring finger and engage and flex the resilient portion and raise the catch 30 sutliciently high in the notch that it. will slide up upon the chamfered portion 3(3 and will then pass over the periphery of the driver until it comes to the next notch when it will drop into such notch, and if the movement of the member 51 continued the catch will be ratcheted out of such notch. il hen the projecting member or actuator 50 is under the. finger 34: and in engagement with the catch 30 this and the notches oi the driving member are caused to assume the relations and functions of a pawl and ratchet, since the chanrfcring is only upon one side of the notches and permits the catch to move in that direction around the driver wheel but the walls on the opposite sides of the notches being unchamfcrcd will actas detents to prevent a reverse movement of the catch.

The first driving wheel 21 will be held during the settin from backward or reverse movement, by means of the detent 29, and the well known form of pinions which con: nect one driver with the other will loclt the respective drivers from reverse movement. The numbenwheels 11, 1. 3, 13, and 14 are respectively provided with projections 51, 52, 53 and The actuator projection 50 upon the plate 37 will act upon the catch of the number-wheel 11. The actuator projection oi oi the number-ring 11 will a t upon the catch 02": the driving ring 12, and so on through the'series. i

Referring to 3 it will be noted that the actuator projection 50 and a projection 55 are carried by the plate BZand that the catch 30 and a projection 5'6 are carried by the number-ring 11. Between the projections 55 and 56 is inserted a compression spring 57 which will immediately upon release of the head 42 by the hand of the operator niove the projection. '50 out from under the finger and permit the catch to sink into the lower portion of the notch 85, so that after the device has been set back the parts will be automatically put in such a position that they can only be moved from such position by the oscillation of the arm 28. As the parts-are being moved around in registering or counting the projections 50 etc. will pass over the by-pass spring fingers without interfering with the proper working of the mechanism. in Fig. 4: this lay-pass movement is being illustrated. In

5 the receding movement of the procensor jection is illustrated and the catch 30 1s shown as riding upon the periphery oi. the

driving wheel between two notches. And

in 10' the projection is shown as hold-- ing the catch in its ratcheting relation to the notches of the driving wheel.

The number-wheel 15 has a projection for engagin a detent 59 when all the wheels are returned to zero. The dctent is in the form of a spring so tliat it will permit the detent to pass it on the forward movc ment of the wheel.
